SPADING AND DIGGING- PLOW.

. Specification of Letters Patent.

Patented July 9, 1918.

Application filed May 19, 1917. Serial No. 169,687.

"of which the following is a specification,

reference being had therein to the accompanying drawing. This invention relates to spading and digging plows and has for its object the production of a simple and eflicient plow which will dig'into the ground over which the same ispassed in the'same manner as a person would use a spade. f

Another object of this invention is the production of a simpleand efficient means for supporting the spades upon the plow A still further object of this invention is the production of a simple and eficient means for holding the blades in an adjusted position whereby the plow'drum 'may be conveniently moved from place to place when so desired. I

With' these and other objects in view, this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings f Figure '1 1s a central section throughthe plow and blade supporting drum.

Fig. 2 is aside elevation of the drum, j

certain parts being broken away. 1

' Fig. 3 is an end View of the drum.

Fig.4 is a detailed perspective of one of the spading blades.

Fig, 5 is a section taken on the line 55 ofFig'Q." I

Fig. 6 is a section taken on the line 66 "of Fig. 2. v

Fig. 7 "s'Ta side elevation of a portion of drum showing the manner in which the locking lever is adapted to hold Ting position.

Fig. 8 isa top plan view of one method of attaching the'digging drum by means of 7 a swivel to a truck.

' Fig. 9 is a top plan'view or diagram of the method of attaching a plurality of these digging drums to a truck.

Referring to the accompanying drawings by numerals it will be seen that 1 designates the central supporting axle, which central supporting aXle engages. or supports the 'outer drum 2 which'outer drum comprises a pair of side plates as clearly illustrated in Fig. 2 of the drawings. An inner drum -3 is keyed to the shaft 1, as illustrated clearly in Figs. 1 and 2 of the drawings and a yoke frame 4 is connected to the outer ends of the shaft 1 for the purpose of'facilitating the conveying of the plow from place to place. The forward end of the yoke frame 4: is connected by means of a swivel joint-5 to the frame of a yoke 6 as illustrated in Fig. 8 when only one of these drums is being used.

When a plurality of these drums are employed, such as for instance when three drums are employed, the rear drums 7 as illustrated in Fig. 9 have their yoke frames a engaging the projecting ends of the axle or shaft 1 of the forward drum 8, as illustrated in Fig. 9. I

It should of course be understood that any suitable or desired arrangement may be employed without departing from the spirit of the invention, whereby one or more of these digging plows may be connected to a'truck.

By carefully considering Fig. 1 it will be seen 'that the outer drum2 supports the transversely extending plow blade supporting shafts 9 near the outer periphery thereof, A plow blade supporting'sleeve 10 is loosely mounted upon each of these shafts 9' as clearly illustrated and each of these sleeves 10 as illustrated in Fig. is provided with a rearwardly extending lip 11 to which lip 11 is connected a coiled spring 12 which coiled spring 12 is connected at its opposite end to the inner drum 3. The tongue 11 is provided with an adjusting bolt 13 and this adjusting bolt adapted to be' re'gulated for engaging a lug '14 carried by one of the plates of the drum 2 to limit the swinging movement Each of these sleeves 10 is provided with a projecting finger 15 through which projecting finger 15 passes the supporting neck 16 of the digging blade 17 of the plow. bolt--18 eirtends through the finger 15 and engages the neck 16 for firmly holding the blade 17in an adjusted position within the finger 15.

A locking lever 19 is keyed to the shaft -1 and is provided with an inwardly projecting lug 20 which lug is adapted to fit in one of the adjusting apertures 21 formed in the outer face .of oneof the plates of the drum 22. This lever 19 is adapted to engage one of the apertures 21 as above stated whereby the shaft 1 may be held against rotary movement. It will be seen that when the lever 19, engages the aperture 21 as shown in full lines in Fig. v2, the drum 3 will be rotated to such a position as to cause the plow blades .17 to be drawnwithin the outer periphery of the plates of the outer drum 2 and thereby permit the outer drum to be easily and readily conveyed from place to place without any danger ofhaving the blade 17 dig into the ground over which the device is passing.

. When, however, the lever v1-9 engagesthe other aperture 21 which is placed at right angles to the first aperture 21-or as shown in full lines in Fig. 7, the drum 3 will be so rotated as to pull the springs 12 forward so as to extend at right angles to the-position shown in Fig. 2 or in other words in the position shown in Fig. 1, thereby causing the blades 17 to project outwardly such as is shown. in .Fig. 1 of the drawings. It should be understood that the lugs 141 will constitute a means for limiting the rearward movement of the blades 17 as thesebolts 13 will prevent the further swinging movement of the plow blades 17 when said bolts engage the lugs ll carried byone of theplates of the drum 2.

V It should; be understood that the tongues ills-are so placed upon, the slceveslO as to have the tongue 11 of every alternate sleeve 10 to be placed upon the opposite end of the sleeve 10 as clearly illustrated in Fig.8 of

' and by means of vthe construction above de scribedand clearlyillustrated, the dirt may be thrown from the digger'blades so as .to efficiently loosenrthe earth which is being en aged bv d gger blades, as a ec f r a d scoop ng ct n wil tak pa ceplace upon therespective dig- 'ging blades 1 4 It should be understood that when the blades 17 are thrown to the position shown in Fig. l, and also in view of the fact that the blades are pivotally supported upon the drum 2 and yieldably connected to the drum 2 engaging said outer drum for rotati ng and 7 locking said inner drum in an adjustedposition withrespect to said outer drum and .changing'the position of said digging blades.

2. A device of the class described comprising an outer drum, a plurality of stop lugs carried by said outer drum, an inner drum, a'supporting shaft keyed to said inner'drum,

said outer drum being loosely mounted upon said supporting shaft, a plurality of blade supporting shafts carried by said outer drum, plow blades carried by said blade supporting shafts and adapted to swing thereon, springs secured to said inner drum,

a sleeve formed upon each plow blade, said sleeve provided with an inwardly extending lip, and saidsprings being secured at their outer ends to the lips of said sleeves and means carried by said lips and adapted to be thrown into "engagement with said stop .ljugs carried by said outer drumlfor limiting V the forward swinging movement. of said lips, and means for rotating said inner drum with respect to saido1 1ter, dru m.
